Awesome! I've been wanting to do actual fluid particle stuff for so long, so it's super awesome we can do this now in Blender 3.1. Thanks for another great tutorial.
Dude. YES. I'm new to Blender and I've found it to be an incredibly powerful yet painfully unintuitive tool. Your tutorial helped me so much and provided a good foundation for subsequent projects. THANK YOU FOR TAKING THE TIME TO DO THIS
Duuuude... Massive props to your teaching skills! Really easy to follow your tutorials. I also love that you explain primitive functions and keyboard shortcuts, even though this is mostly no so important for more experienced users, but for beginners they can be crucial! Thanks for your work!
Great tut, thank you! I'd also recommend looking into the awesome molecular+ addon, it's free and creates particle sims where the particles interact with each other, and can pile up like sand. Thanks as always for the great content!
The only issue I could see is that you'd need A LOT of particles in order to get a super sand-like effect. My PC can handle up to 1million particles so the sand would have to be in small amounts
True, I work with actual sand and usually there is also variation in shape, size of the grains and translucency of grains and they in real life tend to have different magnetic properties so some repel and some attract more. None of it really is that important if you can hide it with good lighting and show from further away, maybe add some motion blur etc. But yes, if one wanted to make sand more like in real life they are not like 3D perfectly printed spheres they are far more random than that. But to be fair even in real life, small grains look similar enough unless you shoot with macro lens or look at it under microscope or magnifying glass, so its quite forgiving for well though out animators.
Looks like the cone is a cheat to make the liquid pile up like sand. Clever. As always, I am in awe of minds that can figure out how to put the infinite number of possible combinations together in meaningful ways.
Awesome! By the way, you can take two separate cylinders and then use loop cuts and increase number of cuts and smoothness (preferably set to smooth). It looks much better and is automatic, rather than manually scaling. (3:10)
Sand is actuallly crystals and are square not spheres I wonder if you can compare then and tell me whch looks better to you. (My hardware is so 1990s it takes days to render what I do)
I have been watching your videos for quite some time now, and I must ask...Do you work with CGI or anything besides making these videos? Because you are god damn awesome at making these things!
Thank you! I do some occasional freelance work sometimes. But I got those freelance projects because of TH-cam, I'd say my skills have gotten better mainly because I make videos, as there is a certain pressure to deliver something good every time.
@@BadNormals It is really great! Keep up the good work, and stay safe from Russia. You are a lot closer than I am, I am in Sweden but I am still worried...
hi, in this metod there is a problem with the scale of the spheres. the particles change scale in each frame. i think a index data is necessary for a correct animation. right?
Great Tutorial, was trying to do an effect like a paint bomb going off and taking a still photo of it as a desktop background, this brought me more than close enough to achieving that I've noticed one issue while following along however: persistence. the random value node in the geometry nodes seems to generate a random value every frame so all the particles change in size every frame. same goes for the random value generated by the point info node in the shader, so the particles also change in color every frame it's not a big issue for me since I'm doing a still shot, but it's not great for animations. looking at your intro it seems that you weren't having these issues so I'm wondering if this is a version difference (maybe the way random values are handled changed at some point between blender 3.1 to 4.1) or if this is something you fixed in the process of making the animation but left out of the video
2:00 to add on to this, if you do need a camera to begin in a still position and start moving, make the bezier LOOOOOOOOOONG. No! Longer! Our eyes are EXTREMELY sensitive to camera movement, so even the tiniest changes will register, and that means the default curves will look way way too abrupt and robotic to our eyes. They might *seem* smooth but they're not smooth enough for cameras! Stretch em out and give your timeline enough room to perform that kind of move. If it feels like it's taking too long to get up to speed, chances are that you should be starting the scene in motion. Only begin a camera move from zero in very rare circumstances
Hey Bad! I've been trying to simulate good sand storms in Blender eevee for the last 2 years and it's very difficult getting both the macro dynamics of wind blowing it with the micro dynamics of it hitting objects. You can do it with smoke, but it looks like smoke. You can composite larger voronoi fractured particles, but the simulation quickly runs out of steam. It looks like they've solved this in 3.1. Finally. Thanks for the simulation. I love how the geometry nodes can have a glassy look. BTW: The colors of sand particles depends on the sand. An hour glass usually has very fine, pure, white sand. In sand storms you use desert sand which is usually a combination of various brown, pink, red and black in various distributions. It depends on the desert and where the particles come from, what they've made of etc. Can you attach geometry nodes to components of a voronai fracture? One last thing, and this is probably the hardest to simulate. What would be required to make the particles actually pile up in a cone rather than forcing the cone shape? Does that require some kind of "sticky" physics attribute so that they scatter a little and pile up. I realize this would make the simulation complexity extremely high as you couldn't get rid of any of the nodes. They would just sit there static. Maybe that attribute that you changed so that only the outside particles were simulated.
Do fluid sims have any sort of 'stickiness' sliders? If you could make the particles more sticky, they'd pile up in more of a cone, right? Not sure if this is a thing yet
Sorry dude, I've stuck in 8:19. I have plane as a collider for these particles and it's simply goes through that plane and if I'll check "Is planar", particles collides above the plane
Vour videos are very amazing sir very informative . You explained so well that I'am in love with your content ,especially the video I saw of dot product I was shocked that I was using blender and didn't even know this, I really hate maths but when you were explaining I was loving and hope others loved that too .In my country they make us to by heart the formula or remember it by tricks and as result we forget it in just 2 years but what you explained I guarantee I'll never forget . Please sir make more videos on math topics covered in blender . Thank you . Also please suggest me material were I can learn these math used in blender for geo nodes
Thank you for the tutorial, I have two problems, my cone only displays inside the glass bottom of the hourglass and the sand floats quite far from the edges of the cone ?
The weird "clumping in the middle" where you deleted part of the hourglass is a natural property of water. I *believe* changing the viscosity to zero would fix this.
So valuable this is! I'm now wondering how you can adjust the amount of grains afterward??? The liquid options in the particle tab no longer seem available once you've executed the geometry node steps.
it was working right until the end, right as I used the particle instances, i can no longer see any of the simulation in render preview. Im using Cycles as well. does this have to do with me using blender 3.0 instead of 3.1? cant figure it out for the life of me
I have put a sphere and cube but, somehow not seeing any blue particles (animation) when aded physics(fluid) to each shape @5:35. not sure what I am doing wrong..
It seems you need an IQ of 500 to find all the work arounds in blender to do something like this; that blender does not do well (or can't do at all). This is very cool, thanks.
I usually take 5 or 6 times to simulate liquid. Then on the seventh time it stops working again. Anyway my thumb is getting tired from giving you so many thumbs up. Thanks and stay safe
NICE very thank you. 1 Question other a one event 》 How to change , custom area texture on scanned pointcloud object. Maybe only logo change. Project texture problem how to use on deform object ??? Thanks
Amazing! Can I ask how you enable the motion blur in the points? I tried enable the motion blur in the render settings, and also tried de vector blur in the composition. Neither one worked =(
hi lets say I have a bumpy ground with a desert shader as a collision object, and I want to have the visual effect of flying sand particles by the wind using mantaflow, is a bit tricky since the sand has a specific connected particles pattern which I find very hard to achieve with the mantaflow smoke basic parameters, i used 2X wind forces to achieve the effect and i played with the domain parameters ut still didn't have the desired flying sand pattern
Can you show the full scene setup with lighting/background/HDRI/Camera animation? Did you use any volume lighting in that shot? Trying to replicate the same.
Fantastic tutorial. I need to do something similar but need the sand to start at the bottom and then flow when the timer is rotated. Would this method work in that instance ?
For some reason, particles on the bottom cone are floating in the air. particles are not touching the cone surface for me. is there something I am doing wrong? I checked the whole video but did found any step that I missed.
Awesome! I've been wanting to do actual fluid particle stuff for so long, so it's super awesome we can do this now in Blender 3.1. Thanks for another great tutorial.

Bad Normals you are awesome! .. we are supporting you from Africa. keep the good stuff
Stunning introduction! Really loving your content.
Great tutorial! Only thing is that sand is actually more sharp and less spherical than you did here.
Soon you can change the shape of the primitive, it's a sphere just currently

you can do that now making multiple particle emission and vary them in and colour and use a rounded cube
Looks like the cone is a cheat to make the liquid pile up like sand. Clever. As always, I am in awe of minds that can figure out how to put the infinite number of possible combinations together in meaningful ways.
One of the few tutorials I kept watching after the default cube was deleted
4:28
I followed your tutorial but I don't see any blue particle :(
That bowl shot is fantastic! So glad you kept it. It really sells the whole video to me. Great job.
thanks again for a superb tutorial higlighting some of the new stuff in 3.1! always stoked for your tuts mate.
Amazing work. Saved my project. Thank you.

Awesome! By the way, you can take two separate cylinders and then use loop cuts and increase number of cuts and smoothness (preferably set to smooth). It looks much better and is automatic, rather than manually scaling. (3:10)
Man these intros are getting damn hollywood grade
You can actually use the old instance method by parent a mesh to it and use the instance feature. That still works in blender
Sand is actuallly crystals and are square not spheres I wonder if you can compare then and tell me whch looks better to you. (My hardware is so 1990s it takes days to render what I do)
That intro was sick!!
Did I really forget to thank you yesterday? Sorry. I'll say it now then. Thank you ❤
Your lighting in that demo vid is just so good looking!
It genuinely looks interesting, rather than my flat 3 point lights :|
Thanks! It's very easy as I told, just squeeze the maximum out of one light and you're good to go.
Thanks for this. I just checked out "what's new" in blender 3.1 and came straight to YT looking for sand tutorial 😆

Hey jvburnes - look into the Molecular+ addon. It allows particles to interact with one another and "pile up", and it's free and awesome!
as anytime i try to do something according to tutorial - from certain moment things stop working as they should to and i never find out why
I am looking for a particle simulation that actually piles up in a cone. Right now with fluids most I can do is something akin to mud.
Do fluid sims have any sort of 'stickiness' sliders? If you could make the particles more sticky, they'd pile up in more of a cone, right?
Not sure if this is a thing yet
So cool! Your videos are always awesome
i´ve been working for this tutorial for months
20:13 I didn't understand how you made the particles round
Really, great work!
however, adding screenrecording keys might be a big time saver :)
You're the BennyProductions for Blender
Now I only need to move to the Netherlands.
Great tutorial as always, well done :O)
wow! this is insane, very clever explanation, thx!
i was able to use the process you did for the cone to make random street lights for a scifi city. thanks
Sorry dude, I've stuck in 8:19. I have plane as a collider for these particles and it's simply goes through that plane and if I'll check "Is planar", particles collides above the plane
You have to check "Is Planar" box inside the Effector. Worked for me, nie załamuj się i jedziesz z tym piachem!
Crazy useful stuff!!!
That opening animation though
Never seen sand that real in Blender!!

Why is my effector colission not working?
got the same problem...any soultion ?
Any compositing tutorials, please?
One about compositing the various render passes in maybe After Effects or Fusion
Blender Bob has a detailed composition tutorial. That might be what you want?
Great tutorial!
Interesting! I didn’t know that is possible with Blender
Thank you for the tut
Thank you for the tutorial, I have two problems, my cone only displays inside the glass bottom of the hourglass and the sand floats quite far from the edges of the cone ?
Cool stuff. Now i hope they just add a particle simulator officially so we don't have to do these hacks.
would be cool making a sand man with this
The weird "clumping in the middle" where you deleted part of the hourglass is a natural property of water. I *believe* changing the viscosity to zero would fix this.
I believe that too, but then the bottom part starts to become too splashy. Depends on the scene.
We hate ads: 0:00
So valuable this is! I'm now wondering how you can adjust the amount of grains afterward??? The liquid options in the particle tab no longer seem available once you've executed the geometry node steps.
Epic intro 🔥

Here's a thumb from me 👍
Please explain the rest of the functions of the Math Node and Vector Math Node.
Hi How do you retain the particles in render, its not showing up in my rendered photo and animation, Please help
it might be that you made your particle system hidden in render, you can change that by ticking the camera button near the name of the particle system
The only thing is, is that sand is more like small cubes in terms of it's shape. Just like sugar
fantastic video. thanks for sharing!

Amazing!
Can I ask how you enable the motion blur in the points?
I tried enable the motion blur in the render settings, and also tried de vector blur in the composition. Neither one worked =(
Why was the liquid off set so far from the edge. I didn't hear anything related to that in the video. Is that a collision setting perhaps?
What a English haha! That’s very cute😂 thanks for your tutorial!
Stupid question maybe but I dont get how change rotate point in edit mode. Period key just input period above (when we write degrees of rotating).

Can we render something else than round particles? Like can we render some flat and some other shape particles?
Fantastic tutorial. I need to do something similar but need the sand to start at the bottom and then flow when the timer is rotated. Would this method work in that instance ?
